Reservists, Guard Personnel at Risk for Alcohol-Related Problems

Higher Risk of Alcohol-Related Problems for Reserve, National Guard Personnel

Younger service members and Reserve and National Guard combat personnel returning from the wars in Iraq and Afghanistan are at increased risk of new-onset heavy drinking, binge drinking, and other alcohol-related problems, according to a recent study in The Journal of the American Medical Association.

Isabel G. Jacobson, MPH, of the Naval Health Research Center in San Diego, and colleagues examined whether military deployment to the wars in Iraq and Afghanistan is associated with new-onset or changes in alcohol consumption, binge drinking behavior, and other alcohol-related problems. Data were derived from questionnaires completed by participants at the beginning of the and follow-up. After the researchers applied exclusion criteria, the analyses included 48,481 participants (active duty, n = 26,613; Reserve or National Guard, n = 21,868). Of these, 5,510 deployed with combat exposures, 5,661 deployed without combat exposures, and 37,310 did not deploy.

The researchers found that among Reserve or National Guard personnel who deployed with combat exposures the rate of new-onset heavy weekly drinking was 8.8%; the rate for new-onset binge drinking was 25.6%; and for new-onset alcohol-related problems, 7.1%. Among active-duty personnel, new-onset rates were 6.0%, 26.6%, and 4.8%, respectively. Among Reserve/Guard personnel, deployment with combat exposures was associated with increased odds of new onset of all three drinking outcomes compared with nondeployed personnel, with heavy weekly drinking (63%) and alcohol-related problems (63%) showing the strongest association.

Among active-duty personnel, those deployed with combat exposures were at increased odds (31%) of new-onset binge drinking at follow-up. Those born after 1980 were at 6.7 times increased odds of new-onset binge drinking and 4.7 times increased odds of new-onset alcohol-related problems. Those with PTSD and depression were at increased odds of new-onset and continued alcohol-related problems at follow-up.

“These results are the first to prospectively quantify changes in alcohol use in relation to recent combat deployments. Interventions should focus on at-risk groups, including Reserve/Guard personnel, younger individuals, and those with previous or existing mental health disorders,” the authors concluded.
